Adjustable security system for bracelets

ABSTRACT

The invention relates to a safety device comprising long elements ( 1 ) which are guided using slits ( 2 ) and grooves ( 3 ). A two-sided button ( 4 ) is disposed between the slits in the long elements ( 1 ) and is used to slide said elements in order to obtain the desired length.

This invention relates to an adjustable security system for bracelets. This invention features elongated parts (1) that slide through each other making it possible to adjust the length of the bracelet to the size of the wrist.

All of the materials applicable to the invention can be used for its production.

CURRENT STATE OF THE TECHNIQUE

Today we are familiar with security systems for bracelets that feature unfolding loops that fold down one over the other. Several patented systems (for example, U.S. Pat. No. 4,424,611, U.S. Pat. No. 5,771,543, No JP10127318. U.S. Pat. No. 23,948,556, show that it is possible to adjust the length of a bracelet. In this case, the adjustment requires the intervention of a jeweler or watchmaker or the use of a specialized tool. In addition, the flexibility of the lengthening is reduced.

The goal of this invention is to bring a new solution to these problems of adjustment by creating elongated parts that can be adapted at any time, with ease and in one simple step. The wearer of the bracelet can thus adjust the length of the bracelet whenever he wishes to fit the size of his wrist, without using any extra object, (such as a tool) and without calling on the help of another person.

Although the patented systems cited above are satisfactory, they in no way feature the same characteristics as this invention.

I have done research with the help of specialists on the web site www.espacenet.ch related to the international patent search, and have found no sliding system similar to my invention.

slots are filled with many illogical and incomprehensible complications, also generates significant productions costs for a questionable result. This in no way resembles the GIORDANO invention, which describes a telescoping system, whose closure is performed by the security system and the hinged cap. The two inventions offer functioning and production systems that are completely opposite.

U.S. Pat. No. 936,697 Gerald William Canston, London, Aug. 26, 1961, An Extensible Link Fastener for a Bracelet or Similar Article of Jewelry

The closure features no security system, since the system can open when the closure is unhooked (FIG. f, part D). In addition, the functioning of the closure depends on a spring similar to the Fessler Patent.

Patent CH1 669 501, Favre, Jacques, La Chauix-de-Fonds, Feb. 26, 1987, Closure with Automatically Adjusting Fold for Bracelets

It describes an unfolding closure one of whose sides contains an opening that serves as a stabilizing guide to pull the bracelet over the unfolding loop. The function of the groove does not have the same goal as that of the groove in the GIORDANO invention. Once again, someone in the business would immediately recognize the difference.

U.S. Pat. No. 6,085,550 Mitsugi Ishida, New-York, Jul. 11, 2000, Adjustable Article of Jewelry and Related Method

This patent refers almost exclusively to ring closures. There is no relationship to the characteristics of the GIORDANO invention.

After having examined the six patents listed above, I have come to the conclusion that none of these patents can claim a telescoping system that possesses an adjustment system that is graduated along its path, in combination with a secure closure, which also permits adjustment to the proper diameter, and opening and closing the wristwatch as easily and simply with a single available hand.

EXPLANATION OF THE INVENTION

For a long time now, users of wrist watches have shown a keen interest in a watch that would offer comfort, beauty, simplicity, and of course, easy adjustment to the wrist, without specific intervention by a jeweler, a mechanic, or anyone else.

Even though the market has already proposed a few solutions, the situation today is not yet really satisfactory, especially due to technical limitations, the bulkiness, or the high production costs of the patented systems. Due to the importance of this need. I have invented a system that is secure and adaptable to wristwatches, ornaments, and other bracelets to which it could apply. The great novelty resides in the fact that the GIORDANO bracelet possesses a telescoping system featuring optimal hooking methods and a closure that is accomplished by a graduated coupling.

After having performed a survey among wristwatch manufacturers, ornament makers, as well as among the professionals of the watch industry and users, the invention had an enormous success and the results seem very promising.

During the Salon International des Inventions in Geneva Apr. 6-10, 2005, I was the winner of the competition and received the 1^(st) prize with Gold Medal, as well as the congratulations of the International Jury, for the invention of the Adjustable Security System for Bracelets, and others.

BEST WAY TO APPLY THE INVENTION

FIG. 1 represents a watch 1, followed by a connecting piece 1, hinged using a pin with a curved section 24.

FIG. 12 represents links 3 with forced methods for coupling due to flexibility 42 and a protrusion 41 and a diagonal groove 43 and an opening 44. The whole mechanism, once assembled, forms a connection between the watch and the telescoping system.

FIG. 3 represents the telescoping system composed of a drawer 12 (FIG. 7), with a method for guiding 5 and 8, followed by a stopping notch at the end of the path 10, all this on both sides of the drawer. The edges of the drawer possess grooves 7 over the entire length put there for coupling with thee cap 25. A second groove 13 (FIG. 8) features two stopping notches 9.

at the end, borders 11, a coupling button 14 with a notch 34, which hooks into slot 20. The movements are done in a synchronized manner.

The second drawer FIG. 8 is guided into FIG. 7 (see openings 5 and 8) in order to slide all the way to the constraint of the notches 10 (FIG. 7) and the notches 9 (FIG. 8). A third piece 15 (FIG. 9), a flexible part 32, through the pins 19, opening 20, with diagonal angles on both sides 31, couples with button 14 (FIG. 8). This button has diagonal angles that are matched with the opening 20, at the diagonal angles 31 (FIG. 9) with a back and forth sliding motion, prolonging and shortening, the length of the telescoping systems. Once the setting up of the telescoping system is complete, part 37 (FIG. 11), already fixed to connection 4, possesses a method for receiving part 15 (FIG. 9), through flexibility 32, which become inserted to facilitate the matching of these pins 19 in the holes 33, to fix and hinge the telescopic system (FIG. 3), the cap 25, and the bracelet 4. Part 37 possesses a method represented by a tong 21, which comes to stabilize and prevent part 15 from pushing out and disconnecting the hinge between the telescopic system, the cap and the bracelet when the security system is used by the wearer. 

1. Security device for a bracelet making it possible for each person to adjust the length of the bracelet according to the size if his wrist, doing so in one simple step, characterized by the sliding effect of elongated elements (1).
 2. Security device according to claim 1, characterized by the holding of the elongated elements (1) by slits (2) and grooves (3) in the elongated elements (1).
 3. Security device according to claim 1, characterized by grooves (3) with stopping notches (7) or conical constrictions.
 4. Security device according to claim 1, characterized by a two-sided button (4) making it possible to fix the elongated elements (1) and aiding in stopping them.
 5. Security device according to claims 1 through 4, characterized by the possibility of using other existing or new fixation systems.
 6. Security device according to claims 1 through 5, represented by a closure featuring a siding part (6 a) with teeth and a fixed part (6 b) with many holes. These two parts slide until the desired length is reached, according to the size of the wrist. Once the size is determined, the sliding part (6 a) and the fixed pat (6 b) interlock laterally thanks to a sliding system, thus blocking the bracelet perfectly.
